  Imidazole Aldoximes Effective in Assisting Butyrylcholinesterase Catalysis of Organophosphate Detoxification

  摘要：

  Intoxication by organophosphate (OP) nerve agents and pesticides should be addressed by efficient, quickly deployable countermeasures such as antidotes reactivating acetylcholinesterase or scavenging the parent OP. We present here synthesis and initial in vitro characterization of 14 imidazole aldoximes and their structural refinement into three efficient reactivators of human butyrylcholinesterase (hBChE) inhibited covalently by nerve agent OPs, sarin, cyclosarin, VX, and the OP pesticide metabolite, paraoxon. Rapid reactivation of OP-hBChE conjugates by uncharged and nonprotonated tertiary imidazole aldoximes allows the design of a new OP countermeasure by conversion of hBChE from a stoichiometric to catalytic OP bioscavenger with the prospect of oral bioavailability and central nervous system penetration. The enhanced in vitro reactivation efficacy determined for tertiary imidazole aldoximes compared to that of their quaternary N-methyl imidazolium analogues is attributed to ion pairing of the cationic imidazolium with Asp 70, altering a reactive alignment of the aldoxime with the phosphorus in the OP-hBChE conjugate.

  Provided are N-alkyl imidazole 2-aldoximes, including cationic imidazolium and uncharged tertiary imidazole aldoximes, and compositions and methods for making and using them, including methods for reactivating human butyrylcholinesterase (hBChE) or acetylcholinesterase (hAChE ) inhibited by organophosphate (OP). By administration of a composition of the invention, the inactive or conjugated hBChE-OP or hAChE-OP is reactivated and the catalytic cycle of turnover and inactivation of the OP is completed; and in alternative embodiments, secondary mechanisms of reversible protection of hBChE and hAChE from irreversible inactivation by OPs and reactivation of tissue AChE also contribute to overall efficacy.

  提供了N-烷基咪唑-2-醛肟，包括阳离子咪唑盐和不带电的三级咪唑醛肟，以及制备和使用它们的组合物和方法，包括重新激活被有机磷酸酯（OP）抑制的人丁酰胆碱酯酶（hBChE）或乙酰胆碱酯酶（hAChE）的方法。通过给予本发明的组合物，不活性或结合的hBChE-OP或hAChE-OP被重新激活，完成了OP的催化周转和失活循环；在替代实施方案中，可逆保护hBChE和hAChE免受OP不可逆失活的次要机制以及再激活组织AChE也有助于整体功效。
